Penaeus (Fenneropenaeus) Perez Farfante, 1969

Type species.

Penaeus indicus H. Milne Edwards, 1837.

Gender of subgenus.

Masculine.

Diagnosis.

Rostrum generally bearing 2-5 ventral teeth. Postrostral carina without median sulcus, sometimes with pits or sunken areas. Adrostral sulcus extending posteriorly more or less to epigastric tooth. Gastrofrontal carina absent. Cervical carina with dorsal end a distance from dorsal carapace. Hepatic carina often absent, if present, ill-defined. First pereiopod with small to minute ischial spine. Fifth pereiopod bearing exopod. Sixth abdominal somite completely lacking dorsolateral sulcus. Telson without lateral spines. Thelycum closed.

Species included.

Penaeus (Fenneropenaeus) chinensis (Osbeck, 1765), Penaeus (Fenneropenaeus) indicus H. Milne Edwards, 1837, Penaeus (Fenneropenaeus) merguiensis De Man, 1888, Penaeus (Fenneropenaeus) penicillatus Alcock, 1905, Penaeus (Fenneropenaeus) silasi Muthu & Motoh, 1979.

Remarks.

This subgenus is unique in the genus by lacking a distinct hepatic carina. Only P. (Fenneropenaeus) chinensis bears an ill-defined hepatic carina while all other species of Penaeus (Fenneropenaeus) lack a hepatic carina. As mentioned in Ma et al. (2011) and Yang et al. (2023), Fenneropenaeus konkani Chanda & Bhattacharya, 2003 is very likely to be an invalid taxon with a deformed rostrum and a synonym of a known species of Penaeus (Fenneropenaeus) .
